Preparation and photocatalytic activity of Mo-doped WO3 nanowires

Tungsten-based nanomaterials (WO 3 & Bi 2 WO 6 ): Modifications related to charge carrier transfer mechanisms and photocatalytic applications

“…The change in morphology from NPs to nanorods and nanowires with the addition of 20 -50 g of K 2 SO 4 for Mo-WO 3 was also reported [78].…”

Tuning of the crystal engineering and photoelectrochemical properties of crystalline tungsten oxide for optoelectronic device applications

“…Mo transition metal doping into the WO 3 structure can enhance the photoactivity of WO 3 nanowires. 96 The photocatalytic activity enhancement is presumed to be the result of the synergetic effects of the crystalline structure and Mo-doping. Although the work did not clarify how the photocatalytic activity of the WO 3 nanowire is increased by doping with Mo, it provides a general outlook on transition metal doping.…”

Synthesis and enhanced photocatalytic performance of WO3 nanorods @ graphene nanocomposites

“…1(a) shows the XRD patterns of WO 3 nanorods and WO 3 @GE nanocomposites, both of which exhibited characteristic peaks of the tungsten oxide (WO 3 ) (JCPDS card no. 33-1387) [5], indicating that WO 3 nanorods did not change during the photoreduction of GO. Any peak of GE diffraction peaks was not observed in the nanocomposites due to extremely small amount of GE used.…”

“…WO 3 nanorods were synthesized via a hydrothermal method [5]. The WO 3 @GE nanocomposites were synthesized via a photoreduction method.…”

“…However, WO 3 nanomaterials are usually not efficient photocatalysts because of the high electron-hole recombination rate [3]. Recently, many attempts have been made to improve the efficiency of electron-hole pair separation in WO 3 nanomaterials, such as doping [4] and composites [5].…”
